Specification of Letters Eatent. Patented June 19, 1917.

Application filed January 5, 1917. Serial No. 140,853.

To all whom it may concern:

Be it known that we, WALTER JEFF W. PASHINSKY, citizens of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented new and useful Improvements 'in Self-Adjusting Shaft-Bearings, of which the following is a specification.

The present invention has relation to a shaft bearing comprehending particularly the self-adjusting type for automatically compensating the wearof the parts, and adapted. for use with rotating shafts of various types, but especially adaptable for power transmission shafting of an automobile, the crank shaft of an internal combustion engine or the like places familiar to those versed with the art.

An object of the invention resides in the production of a shaft bearing of the above stated character of such type as to improve and simplify the construction and operation,

and comparatively simple and inexpensive to manufacture, reliable and efficient in use, and capable of ready adjustment.

A still further object of the invention is the provision of a bearing box wherein the supporting arms are detachably connected thereto, and the parts associated with said arms are adapted to be readily assembled or disassembled, whereby should any of such parts become broken the damage can. be readily remedied by the replacement of an additional part at a minimum amount of expense.

Furthermore, we contemplate providing a cap detachably supported on the arms of the box through the employment of keys and the keys being "so constructed and associated with other parts of the bearing to adapt the cap for automatic adjustment to compensate for the wear of the shaft. 1

With the above and other objects in view, the invention consists in the novel features,

details of construction andcombination of parts which will hereinafter be more fully set forth,-illustrated in the accompanying drawing andpointed out the appended Figure 1 is a perspective view of the connecting rod and its parts assembled for use;

Fig. 2 is a vertical sectional view; Fig. 3 is a perspective view of one of the ke s' I 4 is a detail perspective view of the B. Trrus and shaft box with one of thel arms removed therefrom; and

several views, 5 denotes a connecting rod having formed on one end thereof a shaft box 6 having a semi-circular recess 7 for-the reception of the movable bearing ring 8 in whlch the shaft 9 is inserted. Formed in the opposite side walls 10 of'the shaft boxing is 'a pair of spaced vertically-arranged guideways 11 andthe side and-bottom walls of the lower ends of said guideways being beveled as indicated by the character 12, the

, purpose of which will be hereinafter more fully set forth. Detachably'inserted through 9 each of the guideways 11 is a flat rectangular supporting arm 13 arranged in spaced rela tionilvith p t to the shaft box and to 0? posite sides of the semi-circular recess. The I character 14 denotes a detachable cap projvvided with a semi-circularrecess opening.

out through the under side thereof and adapted to fit over the removable bearing 8. This cap is likewise provided at opposite sides of the semi-circular recess with a pair of vertically arranged rectangular guideways 15 for slidably supporting the cap on the upper protruding extremities 16 of said arms moveinent. The lower end of each of the supporting arms 13 is provided with a head 17 having beveled flanges 18; consequently when the supporting arms are attached to the shaft box, the beveled flanges 18 of the head will engage with the beveled Walls 12 of the guideways 11 and adapt the head to be wedged in the guideways and dispose the headfiush with the outer contour of the shaft tight and firm connection of arm with said shaft box. arms 13 are of a length exbox, forming a the supporting These supporting ceeding the vertical extentof the alined guideways 11 and 15, of the respective shaftbox and cap, whereby penmtting the upper extremiadapting the cap for a vertical sliding.

ties 16 of the arms to protrude beyond the H upper plane of the cap, and these protruding extremities of the arms have formed therein a substantially elongated slot 19. The guideways 15 of the movable" cap open out in the transverse groove 20 formed in the upper end of said cap, and seated within the groove 29 01? the cap and. lengthwise thereof is a ill I the pair of keys 21 having their shanks 22 projected-through and loosely mounted.- in the slots 19 formed in the projecting extremities 16 afthe supporting arm for operatively associating the cap with said boxing. Detachably associatedwith the cap 14; and arranged in the cylindrical axial openingfl of the cap is a post 24 having an ext-eriorly threaded shank 25 and a head 26. The head 26 of the post snugly engages in a recess formed in wall of the semi-circular recess thereof, to prevent any accidental displacement of the post from said cap. This head 26 is lodged between the confronting faces of the cap and one of the faces of the detachable bearing. Each of the keys 21 is provided. with a wedge-shaped head 27 provided with a corn caved recess 28. The purpose of such recess is to permit the keys to clear the shank 24 of the post upon the removal of the keys from the slots 19 of thesupporting arms. Loosely mounted on the post 24. is a rectangular block 29 having downwardly beveled ends 30, the beveled ends 30 of the block coiiperating with the beveled faces 31 of the heads 27. Embracing the threaded shank of the post is a compression spring 32 having one end, bearing upon the upper face of the block 29 ,1 and its opposite end engaging with an adjusting-nut 33 threaded upon the shank 22 of the post, and the purpose of such spring is to exert a pressure on the block 22 for, constantly urging the keys in such a direction as to cause the cap to-press against the detachable bearings and thus automatically compensate for the wear of the bearing parts as well as the shaft. This form of construction of the device permits of the samebeing readily taken apart for repair or lnspectlon, and the tension of the cap can be readlly adpisted by the operation of the nut 33. After the proper adjustment or tension of the spring is acquired, the nut is locked on. the shank of the post by the employment of a cotter pm passing through suitable apertures-34 of the ost. From the foregoing description, taken in connection with the accompanying drawing, the advantages of construction and the method of operation will be readily apparent to those skilled in the art to which the invention relates, and'while we have described the principles of operation of the invention, together with the device which we now consider to be the best embodiment thereof, we desire to have it understood that the device shown merely illustrative, and thatsuch changes may be made when desired as are within the scope of the appended claims.
